print a list of all file types in a folder?

[sohlinux]

I want to print to the screen a list of all file types *.ext in a folder and its sub_folders

so the list will be something like this

avi
txt
jpg
doc

What is wrong with good old

~ $ ls

You might also find the tree command useful.

~ $ sudo apt-get install tree

~ $ tree

yes I know ls and tree but I only want to see the file types not a massive list of everything in the folder and sub_folders as there are 10000s of files

I just want a list like this showing the different file types

avi
txt
jpg
doc

You can get a list of all extensions with the following

find . -type f | sed -e 's/^.*\.\([^\.]*$\)/\1/' -e '/^\//d' | sort -u

First cd to the top directory, it'll then print every unique extension it finds. If a file doesn't have an extension it'll be excluded from the list.

Holy crap, even after 10 years Unix usage, I've never seen a command look like that. Well done.
